Hybrid reflector system for a lighting unit

ABSTRACT

A hybrid reflector system for use in lighting application. The system is particularly well-suited for use with solid state light sources, such as light emitting diodes (LEDs). Embodiments of the system include a bowl-shaped outer reflector and an intermediate reflector disposed inside the bowl and proximate to the light source. The reflectors are arranged to interact with the light emitted from the source to produce a beam having desired characteristics. Some of the light passes through the system without interacting with any of the reflector surfaces. This uncontrolled light, which is already emitting in a useful direction, does not experience optical loss normally associated with one or more reflective bounces. Some of the light emanating from the source at higher angles that would not be emitted within the desired beam angle is reflected by one or both of the reflectors, redirecting that light to achieve a tighter beam.

FIG. 1 is a perspective view of a lighting device according to an embodiment of the present invention.

FIG. 2 is a front view of a lighting device according to an embodiment of the present invention, with the rear view being substantially identical in ornamental appearance.

FIG. 3 is a right side view of a lighting device according to an embodiment of the present invention, with the left side view being substantially identical in ornamental appearance.

FIG. 4 is a top view of a lighting device according to an embodiment of the present invention; and,

FIG. 5 is a bottom view of a lighting device according to an embodiment of the present invention.

The broken line showing of the bottom portion is included for the purpose of illustrating only and forms no part of the claimed design.
